We are investigating the cause, but it is not clear yet.
It seems that there's memory leak on active check process.

The memory leak occurs when:
- log[] or logrt[] item uses a global regexp consisting of several (at least 2) subexpressions,
- the first subexpression checked is of type "Result is TRUE" and matches (exact match is TRUE),
- the next subexpression checked is of type "Result is TRUE" or "Result is FALSE" (whatever TRUE/FALSE)
There are no Sub-Tasks for this issue.
